Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a continuous stamping die. Background Technology

[0002] Continuous stamping dies are high-efficiency dies that complete multiple stamping processes sequentially within a single die. During operation, the strip material advances between multiple stations at predetermined intervals, with each station performing operations such as punching, blanking, bending, and drawing, thus completing the stamping of complex parts in one go. It consists of working parts such as punches and dies that directly act on the material, positioning parts that ensure the precise placement of the material, unloading and ejection devices that separate the workpiece from the scrap after stamping, and guide parts that maintain the accuracy of the die's operation.

[0003] However, existing stamping dies suffer from two problems: firstly, the strip material is prone to displacement during the stamping process, resulting in unstable product quality; secondly, traditional stamping dies rely on manual operation or external equipment for material feeding, which is not only inefficient but also significantly increases production costs.

[0004] To address these issues, we provide a continuous stamping die. Utility Model Content

[0029] The fixing assembly 400 includes a top frame 401 fixedly connected to the top of the upper mold 600 and two lower clamping frames 404 fixedly connected to the top of the base plate 100. The bottom of the top frame 401 is fixedly connected to two fixing plates 402. The interior of each fixing plate 402 is equipped with an upper clamping frame 403 corresponding to the lower clamping frame 404. The material strip can be clamped by the lower clamping frame 404 and the upper clamping frame 403, which makes the stamping process more stable and ensures product quality.

[0030] Specifically, the upper clamping frame 403 includes two sliding columns 403b movably sleeved inside the fixed plate 402. The bottom of the two sliding columns 403b is fixedly connected to a clamping plate 403a. The outside of each of the two sliding columns 403b is movably sleeved with a buffer spring 403c, and both buffer springs 403c are located at the bottom of the fixed plate 402. The top of each of the two sliding columns 403b is fixedly connected to a top cap 403d.

[0031] Furthermore, an upper rubber pad 405 is fixedly connected to the top of the lower clamping frame 404, and a lower rubber pad 406 is fixedly connected to the bottom of the clamping plate 403a. The upper rubber pad 405 and the lower rubber pad 406 can increase the friction force, making the material belt more stable and preventing damage to the material belt.

[0032] The operation process of this embodiment is as follows: when it is necessary to fix the strip, the upper clamping frame 403 is moved down by the downward pressing of the top frame 401, so that the strip can be clamped on the top of the lower clamping frame 404, thereby making the stamping process more stable and ensuring product quality.

[0033] Example 2

[0034] Please see Figure 1 , Figure 3 and Figure 4Based on the first specific embodiment, the conveying assembly 500 includes a mounting frame 501 fixedly connected to the top of the base plate 100. The mounting frame 501 is rotatably connected to a lower rotating shaft 502 and an upper rotating shaft 504. A lower conveying wheel 503 and an upper conveying wheel 505 are respectively fixedly sleeved on the outside of the lower rotating shaft 502 and the upper rotating shaft 504. A lower gear 506 and an upper gear 507 are respectively fixedly connected to one end of the lower rotating shaft 502 and the upper rotating shaft 504, and the lower gear 506 meshes with the upper gear 507. A drive gear 508 is rotatably connected to the outside of the lower rotating shaft 502. A rack 510 that meshes with the drive gear 508 is fixedly connected to the outside of the fixing plate 402. An orienter 509 for controlling the rotation direction of the drive gear 508 is installed at the other end of the lower rotating shaft 502. By rotating the lower rotating shaft 502 and the upper rotating shaft 504, the upper conveying wheel 505 and the lower conveying wheel 503 can be driven to rotate in opposite directions, automatically conveying the material belt and avoiding the use of additional conveying equipment.

[0035] Specifically, the orienter 509 includes a central disk 509a fixedly connected to one end of the lower rotating shaft 502. The central disk 509a has an installation port 509b on its outside. A locking block 509c is rotatably connected inside the installation port 509b. An ejector spring 509d is fixedly connected between the locking block 509c and the bottom of the installation port 509b.

[0036] Multiple ratchet teeth 508a are fixedly connected at the center of the drive gear 508, and a locking block 509c is engaged in the tooth gap of the ratchet teeth 508a. The locking block 509c is engaged in the tooth gap of the ratchet teeth 508a by the push-out spring 509d, thereby driving the lower conveyor wheel 503 to rotate.

[0037] Furthermore, a hexagonal socket 502a is provided at the end of the lower rotating shaft 502 away from the lower gear 506. A hexagonal prism 509e that is compatible with the hexagonal socket 502a is fixedly connected to the center of the back of the central disk 509a. A fixing screw 511 is movably sleeved inside the hexagonal prism 509e, and the fixing screw 511 is threaded into the inside of the lower rotating shaft 502.

[0039] The operation process of this embodiment is as follows: When the conveyor belt needs to be conveyed, the top frame 401 first presses down to drive the rack 510 to move down, thereby driving the drive gear 508 to rotate. Then, the drive gear 508 drives the lower rotating shaft 502 to rotate through the locking block 509c that engages with the tooth gap of the ratchet 508a. Subsequently, the meshing lower gear 506 and upper gear 507 drive the upper rotating shaft 504 to rotate in the opposite direction, thereby causing the upper conveyor wheel 505 and the lower conveyor wheel 503 to rotate in the opposite direction. This can realize automatic conveying of the conveyor belt, avoid the use of additional conveying equipment, and reduce costs.
